loopback, app engine, json error,, (data limit?)

[yeom...@gmail.com]

I delpoyed an loopback web server on google app engine to communicate with Android client.
However, Android does not fetch the data or parse json once the data exceeds about 150kb.
And on the web, json is fetched with a problem..

Another thing is everything works fine when tested in a local envionment and on other compute engines such as google compute engine and aws. However, when deployed through app engine, my android client (loopback andorid sdk, repository.findAll) does not seem to be able to bring the data(json) to the client with an error that says 'expecting a json array....'

Is there anything to do more specifically when deploying loopback on app engine other than normal deploying process??

it fetches data fine when done through simple http connection on the android...
